Question

Help me with number 6 please thanks just need answer no need explanation n

Answer 1

Given: A cone of the height of 15 meters and base diameter of 40 meters.

Required: To determine the volume of the cone.

Explanation: The volume of the cone is given by-

`V=(1)/(3)\pi r^2h`

Here,

`\begin{gathered} h=15\text{ m} \\ r=(40)/(2)=20\text{ m} \end{gathered}`

Hence, the volume of the cone is-

`V=(1)/(3)*3.14*(20)^2*15`

Further solving as-

`\begin{gathered} V=3.14*400*5 \\ =6280\text{ m}^3 \end{gathered}`

Final Answer: Option B is correct.
